A bicycle store costs $2800 per month to operate. The store pays an average of $80 per bike. The average selling price of each bicycle is $160. How many bicycles must the store sell each month to break even?
The store must sell bicycles each month to break even
(Type a whole number.)

Let x = quantity of bicycles

($160x) - ($80x) = $2800. To solve for x, we have to combine the terms on the left side.

$80x = $2800. Divide each side by $80.

x = 35.

35 bicycles must he sold each month to break even.

Number 5.)
A.)
First, we would want to make an equation. Aiden knows that each nickel is 3.2 grams. He also knows that his collection is 185.6 grams. Therefore, his collection can be represented by the following(x being equal to how many nickels he has)
3.2x=185.6
You can find out how many nickels he has by isolating the variable. In this case, you would simply divide each side by 3.2. Giving us:
x=58
Aiden has 58 nickels in his collection.
B)
This is built off number 5. A nickel is five cents. Aiden has 58 nickels. To find the total amount of change he has, we can make the following equation:
5(58)=y
Then simply
Aiden has 290 cents. Or 2 dollars and 90 cents.
I don’t know how to solve the rest. Sorry!
